PROJECTIN'G MACHINE.

Application filed February My invention relates; to projecting machines, and aims to provide certain new and usefulimprovements in connection with a device of this character,

it is a well appreciated fact that any number of attempts have been made to provide a system which will permit of the proction of pictures upon a screen, and also "ovide sound. reproduction which would yiichronize with the movement of the fignres depicted by the projecting apparatus, to permit of a clearer visualization of the perfornnince being rendered.

These devices *for the most part have proven impractical in that great difficulty has been experienced in properly synchronizing the movement of these two different apparatus working in unison. aside from theexpense involved, it being noted in this connection, that the apparatus embodied for producing the ellect desired, is, in most 1nstances very complicated, and involved the outlay of considerable expense in both its installation and maintenance,

Also although it might prove of commercial advantage to produce aunit of the nature aforedescribed, which would be capo bio of use in the home, it has been impractical to endeavor to place such a. unit upon the market in view of. the con'iplication of" the parts of the some and their relatively great cost,

Entirely aside from the foregoing, it is also well understood that great difficulty has heen exlpcrienced in connection with projecting machines in that it has. been necessary utilize a delivery andreceiving reel, as well asoctuating mechanism for the film which would permit of a projection of pietures simulating motion. Thus the latter spparatus has also involved a relatively great outlay, it being also noted in this aim nection that it has been necessary to utilize a film of a relatively great length to in sure unintelligent reproduction.

Having these defects in mind, it is a prii'nary object of my invention to'provide a projecting machine preferably associated with a sound reproducing unit in such a manner that the movement of these two elenieuts. will be properlysynchronized.

A further object of my invention is the production ofa device of this character in i'i'hichall complication will be eliminated 12, 1921. Serial N0, 444,547,

and by means of which an article may he placed upon the market suitable for home use, and at a nominal figure.

Another object of my invention is the construction of a projecting machine which shall he sii plilied in such a manner as to insure reliability of operation and the slimination of complication,

Still another object of my invention'is the construction of a device'ol the character statedin which a novel type of film may be employed eliminating a great amount of the bulk of the usual film, although insuring an intelligent and relatively long reproduction,

Further objects of my invention will ap pear in the annexed specification and draw ings which letter present one practical embodiment of my invention, and in which:

Figure l. is a sectional side view taken through a device constructed in accordance with my invention, and token along the lines l.l of Figure 2.

Figure 2 is a view thereofo Figure 3 is a partly fragmentary sectional plan view taken through a projecting machine embodying my improved construction.

l igure i is on enlarged sectional view taken along the line 4-4 and in the direction of the arrows indicated in Figure 3 Figure 5 is a fragmentary sectional side view taken along the line 55 in the direction of the arrows elso indicated in Fig ure Figure (l is a view similar to Figure 5,

but showing the parts in slightly different position, and

Figure 7 is a front view of a projecting machine and showing my improved type of {film applied thereto,

'ljel'erring now more particulsrly to Figj 'ures 1 and 2, it will heiseen. that, according to my improved construction, andwith a view of providing a unit utilizing a projeoting and sound reproducing unit ll aim to partly fragmentary plan employ a sound reproducing unit in the nature of a phonograph, and aprojecting machine of my improvedconstruction, herematter more fully described, these elements being properly coupled one to the other, to,

properly synchronize the motion of the some,

It is also to be noted. that ii the device is employed for home use, and to further elimi ing machine.

ill

nate complication, that I also further preferably utilize a part of the sound reproducing mechanism as a surface against wh ch the light rays of the projecting machine may be directed.

Thus referring more particularly to Figure 1, it will be seen that the reference numeral indicates the cabinet of a conventional reproducing machine, having a lid 11, and enclosing a turntable 12 driven in the usual manner by mechanism 13 through a spindle 14, and also having a co-operating tone arm 15 for the conventional purpose. It will be noted, however, that a shaft 16 is provided, which shaft is coupled to the operating mechanism 13 by any suitable means such as a beveled gear 14, co-operating with a similar gear 18, associated with the turn table 12.v The shaft 16, as has been indicated in Figure 2, also provides gears 19 serving to operate a projecting machine 20.

Thus it will be seen that a single source of power serves to operate both the turn table of the talking machine, and 'the projecting machine, and it will be noted, attention being had to Figure 1, that the lid 11 serves a practical function, in that the under surface of the same may be disposed'at an angle at which it will act as a screen for the lightrays emanating from the project- From the foregoing it will be appreciated that the two units (the sound reproducing and projecting) are synchronized in movement and power driven, and that the entire structure presentsanextremely compact appearance in that the lid 11 dispenses with the necessity of providing an extraneous screen serving as a reflecting surface against which the pictures may be projected.

Referring now more particularly to the details of the projecting machine structure, it will be noted reference bein had 'to Figures 3 to 7, that the same includes a drum 21, enclosing a source of illumination 22, the rays of which pass through anopening 23 arranged between the reflecting surfaces provided by the lid 11, and the source of illumination: 22.

Also disposed within the .body of the drum, are a pair of levers 24 swingingly and slidingly mounted as at 25 adjacent one of their ends, their opposite ends preferably including a quadrangular guide way 26.

An element in the nature of a comb 27 is mounted between the outer ends of the levers 24, and the teeth 28 of this comb extend through slots 29 formed through the body of the drum 21.

A shaft 30 has one of its ends projecting beyond the drum, and eo-operates by means of the gear 31 with the gear 19 of the shaft 16. Thus upon the turn table 12 being roteted it will be obvious that a rotation of the shaft 30 will be effected. The shaft 30 mounts cams 32 which latter are disposed one within each of the guide ways 26, and it will thus be noted that a movement is imparted to the comb 27 which will primarily be outward as in Figure 4, upward, rearward and downward as in Figure 5, downward and outward as in Figure (3, subsequent to which the parts will again assume the position illustrated in Figure 4;.

Assuming now that a film is looped over the drum 21 and that such film is provided with perforations capable of aligning with the teeth 28 of the comb 27 it will be seen that such a film would be moved with respect to the drum and intermittently, as is neces: sary to produce the allowance of a constant motion by a projected picture.

This function is to be predicated upon the fact that the teeth 28 will engage with the perforations of the film, move the same upwardly from the position illustrated in F igure (5 to that in Figure -i, and beyond this position, subsequent to which the teeth of the comb would disengage the perforations, and be moved rearwardly and downwardly so that they again might occupy the posi tion illustrated in Figure 6 to repeat the entire operation.

As in ordinary projecting machines, a shutter is necessary to interrupt the projection of the li ht rays during that brief interval in which the film is being bodily shifted, and thus I conveniently mount a shutter 33 in advance of the source of illumination 22, such shutter being coupled as at 34 with the shaft 30 insuring a proper operation of the parts.

' To now furnish a proper film for use inconnection with my projecting machine, and

at the same time to avoid ditliculties incident.

indicated 'in' the figure referred to.

Thus the opening1 23 being of a size equal lm to be exposed, at one to the area of the time, it will be seen that the bodyot' the film will be fed past the opening 22 and this operation will be continued to a point at which the end of the body 35 is reached.

Instead, however, of the part of the film just projected being repeated, .it will' 'be noted that the second rowof pictures upon the film will be projected. and this operation will be repeated until finally the rear lib off-set end of the body portion is moved beyond the opening 23.

With a view of accommodating the move" 38 to the drum 2i and beclamped in proper spaced relationship thereto by any suitable meanssuch as 39, it being noted that slots 40 are provided into which the teeth 28 of the comb 2? may project to move the film bodily.

Thus it will be seen that I have provided, as a single unit, a sound reproducing and projecting mechanism which although not limited to this particular purpose is ideally adapted for home use, and in which all 'complication has been eliminated,although the elements are perfectly synchronized in operation.

It will also he noted that an improved projecting machine is provided, which of course may be used independently of the sound mechanism, which is ideally adapted for use in that it eliminates all complication in connection with the feeding, receiving and projecting of the film.

Also by virtue of the improved type of film provided, by means of my invention, it will be noted that the conventional feeding and receiving reels may be dispensed with and that although an endless film is prm'ided,that the same will permit of a projection for a relatively great length of' time.

Obviously numerous modifications of structure might readily be resorted to without in the least departing ti om the spirit of my invention, which I claim asv k l.
